  "abstract": "The demand for new apple cultivars, particularly red-flesh varieties, has surged in recent years. Fruit red-flesh coloration results from anthocyanin accumulation and is regulated by genetic, developmental, and environmental factors. While the effects of climatic factor such as light and temperature have been studied, their combined and dynamic impacts on coloration at harvest under orchard conditions remain poorly understood. To investigate genotype × environment interactions, we implemented a non-targeted, multi-site approach based on six red-flesh genotypes cultivated across five sites with contrasting climates. Using image analysis and climatic data, we developed statistical models to determine the implication, the ranking and the combined effects of climatic factors on red-flesh color intensity depending on fruit developmental phases. Our results highlight the key roles of maximum air temperature, difference between day and night temperatures, and relative air humidity in red-flesh color development. We characterized their combined effects and identified optimal climatic ranges according to the fruit developmental phase. Finally, we identified significant genotype × environment interactions highlighted by allele-dependent responses to climatic conditions.",
